Abstract
Research on the utilization of industrial waste and agricultural materials to be processed into building materials has been largely done. This encouraged us to utilize water hyacinth as cement board material, because other than as a nuisance plant is also a waste. The purpose of this study was to determine the flexural strength of cement board water hyacinth and the influence of composition variation on flexural strength. Cement board made of water hyacinth measuring 53cm x 5cm x 1cm, and totaled 54 specimens consisting of six variations of composition with a ratio of water hyacinth: glue: cement is 1:1:1, 1:1:1.5, 1:1:2 , 1:1:2.5, 1:1:3, 1:1:3.5, each variation of 9 specimens. Making samples stage of preparation materials including water hyacinth which has become the raw materials of fibers, adhesives, cement and water. Furthermore, mixed materials in accordance with the planned composition. Then insert into the mold and dipressing with concrete block weighing 300 kg during 24 hours. Then dried under the sun 14 days. After that phase of testing by using a simple bending test. From the results, namely flexural strength of 15,858 kg/cm2 at the composition 1:1:1, 22 710 kg/cm2 at kompoisis 1:1:1.5, 1:1:2 22 998 kg/cm2 at kompoisis, 38 342 kg/cm2 at kompoisis 1:1:2.5, 1:1:3 24 528 kg/cm2 at kompoisis, 27 083 kg/cm2 at kompoisis 1:1:3.5. This shows the influence of composition variation on flexural strength.
